Hondo1978 posted a topic in Power AddersAny input on the swapping in of a 6.1 OEM cam to my 5.7 '08 mill? I intend on staging various upgrades to run a 78/75 mm turbo on the street / strip. I am told, stock performance cams work fairly well, due to smother cam profiles. Any knowledge on the cam swap, like valve spring changes, do 6.1 valve springs do the trick out of the box?
